TIRE FLA?.

Application led August 9, 1922. Serial No. 580,652.

To all whom it may concern.'

a specification.

This invention relates to flaps for insertion between the inner tube and the rim casing beads of a pneumatic tire, and it for its object to provide a simple and and has durable article of this nature which can be readil ,applied and removed, and firmly retaine in its proper position.

Of the accompanying drawings, Fig.

lis

a side elevation showing a preferred form of my improved iap.

the

Fig. 2 is a longitudinal section at joint. p

Fig. 3 is a section on the line 3-3, partly in perspective.

In the drawings, 10 is a trough-shaped flap, here shown as made up of inner outer surface plies 11, 12, of straight-laid,

and

woven fabric, and an intervening layer 13 of suitable material, such as rubber and ground fiber composition, all ,parts being vulcanized together.

I do not, however,

limit myself to this particular construction.

A piece of the plied-up Hap material having the desired length is cut oif from alon (er length, and the ends are overlapped :i

as indicated in the upper portion of Fig. 1 and in Fig. 2 when the flap is in place in the tire. at the tire valve, but in this case I ove It is customary to overlap the ends rlap them at a different place, preferably at a point opposite to the valvehole 14, and thus avoida double thickness at the valve where the diameter of the .inner tubeV is already reduced by the on the valve. hrough one end 15 of iesence of the retaining lug the flap is inserted the male member 16 of an ordinary snap fastener, with its head jecting outwardly in the bottom of trou h at the middle line of the flap,

in t e other end 17 are affixed a series of female members 18 of snap their open ends exposed on pro- the and lonhese CaSe S0 terent lengths to accommodate itself to the particular tire in which it is used.

The mode of operation will be obvious from the foregoingy Either before or after the tube is inserted in the casing, its valve stem is slipped through the hole 14, the ends 15 and 17 are brought together and overlapped at the opposite side, and the fastener member 16 is engaged with that one of the complementaryv fastener members 18 which will adjust said flap to the necessary length. In this'way, a fioating iap is provided which is firmly anchored against circumferyential'moveifient on the tube and which cannot change substantially in length after it has once been adjusted, so that the tendency of vsuch liaps to Work up out of place between the tire and tube in either direction from a middle position is to a large extent fully overcome.

I claim:

1. A iap for pneumatic tires having a hole for receiving the valve stem ofl the inner tube, and having overlapped ends at a different locality than said hole, and positive means for detachably securing said ends together in. such manner as to prevent circumferential movement of said ends with relation to each other.

2. A floating fiap for pneumatic tires having overlapped ends, and members of snap fasteners on the respective ends for detachably securing them together, said membersl being of such character and so mounted as to present 'no abrupt irregularities of surface to the inner tube when in fastened relation.

3. A floating flap for pneumatic tires having overlapped ends, a member of a snap fastener mounted onone end, and a longitudinal row of complementary' members of sna fasteners mounted on the other end, sai members being so positioned on said fiap that the first said member may be engaged selectively with all of said complementary members and the Hap held circularly extended without exposure of the detachably-engaging portion of any of said members on the side of the structure contactiig the inner tube.

formed with a hole for receiving the valve stem of the inner tube, and having overioating iiap for pneumatic tiresl lapped ends substantially opposite said mounted on one of said ends and having its valve hole, and positive means for detachdetachably-engaging portion on the outer ably securing said ends together in such side of the flap, and a longitudinal row of manner as to prevent circumferential move- Complementary members of snap fasteners 5 ment of said endsi mounted on the other end for detachably se- 15 5. A floating Hap for pneumatic tires curing said ends 'together'.

formed with a hole for receiving the valve In Witness whereof have hereunto set stem of the inner tube and having overmyhand this 3d day ofAugust,1922. lapped ends substantially opposite said 10 valve hole, a male member of a snap fastener JOHN R. GAMMETER.
